Contributed modules

●Contributed modules are either created for in
house requirement or sponsored project
●Sponsored projects usually have multiple
contribution candidates
We look for unique and generally applicable
●

modules to contribute
●Drupal contributions require maintenance,
although most are productionready


Why we contribute

● To give back to the Drupal community
● To improve the code
● To learn and gain experience
● To free the code
● To be a good citizen


Contributions require maintenance

● Drop'n dash contributions = bad karma
●Therefore, we try to respond to issues,
incorporate patches and rollout new features
●This comes down to prioritising Community
above paidservices, allocating resources & time
● An imperfect juggling act
●Modules not maintained will be claimed by others
(lesson learnt)


Module: Signwriter
htttp://drupal.org/project/signwriter
● Use Case:
– Dynamically create graphics using true type
fonts and text from page
– No more Photoshop'ing
●Signwriter created to solve problem of great
graphic design (poor web design)
● Module used on most Agileware websites


Module: Signwriter

Dynamically replace any text element on a page
●

with a nicely rendered image with alt text
●Can set font (ttf), font colour, size, background
colour, transparency, background image (can write
on images)
Use Signwriter to create an Input Filter and
●

Regex replacement, or
● Insert Signwriter code directly into your tpl files


Module: Signwriter
● Stable, good feature set and easy to use
● Drupal 4.7, Drupal 5 and Drupal 6
●Recently underwent major refactor by eMPee584
(node/316295), thanks mate!
●Now D6 version allows replace page/block titles,
font/style preview, coder style, unicode handling
and more


Module: Signwriter
●Example 1: Replacing the page title in your
theme
● Create a signwriter profile in drupal called 'Theme
Heading', and assign the other settings to your
liking.
Add the following code to your page.tpl.php
●

where you want to print the page title.


<?php
      if ($title != '') {
          $profile =
signwriter_load_profile('Theme Heading');
          // $profile>fontsize = 43; //
override the font size
          print
signwriter_title_convert($title,
$profile);
      }
      ?>


Module: Signwriter
● Example 2: Using Signwriter without a profile
●Add your custom font to your theme directory. In
this example we'll use Arial.ttf.
● Add the following code to your page.tpl.php.


<?php
      if ($title != '') {
          $profile>fontfile = 'Arial';
          $profile>fontsize = 15;
          $profile>foreground = 'ff0000'; // red
          $profile>background = 'ffffff'; //
white. If your text is jagged then change this to
your page background colour
          $profile>maxwidth = 600;
          $profile>transparent = true;
          print signwriter_title_convert($title,
$profile);
}
?>


Module: Signwriter
● Demo


Module: Open Office Exporter

● Use Case:
– Perform Mail Merge feature using Open
Office and Drupal
– Converts Drupal data into Open Office text
●Used by Agileware to generate quotes, invoices,
contracts and other documentation
●Fast, platform independent, no Open Office
required serverside



● Requires CCK module
Drupal 5 only currently, Drupal 6 RSN. Maybe MS
●

OpenXML in future too
● Setup
– Add Open Office CCK field to node type
– Insert code to export Drupal data
– Open Office doc must have matching fields



● Demo


Module: EditView
htttp://drupal.org/project/editview
● Use Case:
– How to add, update, delete records based
data quickly
– Customer wants MS Excel like functionality
on website
● Sponsored project for completing complex survey
●Perform CRUD ops on Nodes and uploads,
images, dates (JSCalendar), Events


Module: EditView
● Drupal Views plugin adds new Views type
● Turns any Views node data into editable rows
● Can be used in onetomany relationships
● Obeys required field rules
● Easy to setup and to use
Drupal 5 only, no Drupal 6 yet. Not compatible
●

with Views 2 (rc++)


Module: EditView
● Demo


Module: ComputedField
htttp://drupal.org/project/computed_field
●Use Case: Need to calculate field value based on
other CCK fields or some other factor
●CCK field type that allows insertion of PHP code
to evaluate a field value (or do anything!)
●Concept is based on Lotus Notes, Computed
field type (don't laugh!)
●No longer need custom mini/generic modules to
alter the node data. ComputedField solves this
problem.


● Code is part of the node type CCK fields
● Easy to manage, can be exported/imported
● Hard to debug
●Assumes you know what you are doing, it's just
PHP code with no helpers
●Can use to either: Store calculated value in
Drupal, or only display calculated value (not
stored) Views


● Example ComputedField:
$node_field[0]['value'] = $node
>field_product_price[0]['value'] +
$node>field_postage_price[0]
['value'];

●Lots of code examples at
http://drupal.org/node/149228


● Demo



● Use Case:
– Define multiple regions of interest on a
Google Map
– Users can click on region for more
information (from related nodes or taxonomy)
– Each region defined by arbitrary points
creating a polygon
Sponsored project to map regions on Google
●

Map.



● Patches to Gmaps and Location modules
● Uses the existing Gmap view type
Adds feature to select marker or polygon for the
●

Google Map
●Ability to assign multiple points on a single map,
instead of the default multiple maps, single point.
● Works with current Gmap and Location modules



● Demo
